The additional horsepower yields faster cycle times and a productivity increase of up to 18%. Intended for mining applications, this dozer also comes with structural enhancements for increased durability of the mainframe and track frame. The D375A-8 also features an improved suspended undercarriage, larger viscous cab mounts, and a new air suspension, heated and ventilated seat for overall operator comfort. Under the hood, the  powerful Tier 4 Final SAA6D170E-7 engine produces a net horsepower of 455 kW in the forward direction and 555 kW in the reverse direction. No selective catalytic reduction system or diesel exhaust fluid is required. The turbocharger has variable geometry that improves low speed response and boost. The engine features a high pressure, common rail fuel injection system and is fitted with dual Komatsu diesel particulate filters. The D375A-8 comes with an automatic, three-speed transmission with an automatically engaging lockup torque converter provides increased fuel efficiency and faster ground speeds during long pushes. Komatsu has also made changes to suspended undercarriage, cab isolators, operator seat, and ergonomics of operator interface significantly improve operator comfort and yield more productive shifts. Structural enhancements of track frame and mainframe increase major component life. Standard features such as blade auto-pitch, ripper auto-return, and shoe slip control reduce operator fatigue and increase productivity. LED lighting is also standard. Many other features improve the maintenance experience. Komatsu offers a state-of-the-art parts and service program to support its equipment.
